On the Revenue Summary tab of a constituent's Revenue and recognition view, there is a "Revenue by year" breakdown that shows the number and amount of transactions each year. These totals can be broken down by Calendar year or Fiscal year, depending on which option is chosen in the Breakdown filter.
